Abstract

The purpose of this study was to experimentally investigate the effects of curing methods on the compressive strength and tensile behavior of alkali-activated slag-based fiber-reinforced composite with a water-to-binder ratio of 15%. Three kinds of mixtures according to the curing conditions were prepared and compressive strength and tension tests were performed. Test results showed that the compressive strength and the first cracking strength of composites decreased when high temperature curing and air curing were adopted, while tensile strain capacity of composites increased. It was also observed that crack spacing and crack width of composites decreased by applying high temperature and air curing.

이 연구의 목적은 양생조건이 물-결합재비가 15%인 알칼리 활성 슬래그 기반 복합재료의 압축 및 인장거동에 미치는 영향을 실험적으로 조사하는 것이다. 이를 위하여 양생 조건을 다르게 하여 실험체를 제작한 후 압축강도와 인장실험을 수행하였다. 실험 결과 고온 양생과 기중 양생을 적용함에 따라 매트릭스의 압축강도와 균열강도는 감소한 반면 인장변형성능은 증가하는 것으로 나타났다. 또한 고온 양생과 기중 양생을 통해 복합재료의 균열 간격과 균열폭이 감소하는 것으로 나타났다.
